All those directories are long gone and dead. Google penalized link farms with several of their past algorithm updates and many of these sites were probably de-indexed. It is best to avoid ANY free directory now, only look at paid directories for backlinks. I would only submit to paid directories because they are normally human edited and of high quality. No webmaster is going to spend money by submitting to a directory that is not quality. This way, you can almost guarantee the websites linking in are quality sites, which will benefit your SEO efforts by paying for a link submission.
